Played Assassins Creed 3.

Performance was relatively rather low. Had to make all settings on normal (as opposed to High or Ultra) - otherwise if on higher settings significant lag or graphics issues, especially in daylight scenes. Overclocking did not seem to help at all. Lowering resolution did nothing to increase performance. Using CCC 12.10.

Haven't tested any other games. (Hard to find time to play games - this was the first time playing a game since I built the system 4 months ago!!)

However it was still awesome to play in HD 1080p on a 50" screen! And on normal graphics it was still HD and looked rather awesome.

UPDATE: Just tested on the 24" monitor, same graphics issues on Very High (ultra) mode for AC3.

1080p on a 50" screen will have the same performance as a 1080p 27" screen. Because its still 1080p...
Also assassins creed will run like a dog anyway.

Not true, not true at all. Runs in Ultra maxed out on 24" screen 1080p with my hardware.
It's processing the same resolution, so screen size means nothing in terms of performance. It should run as smooth as it does on your monitor, if not then there's something horribly wrong, this is from experience also as I have a 42" inch right beside my desk which duplicates my display when I want to play on a bigger screen and listen through the home theater audio.

Then it will run maxed out on any other 1080p display. If it doesn't than you're...

Not true, not true at all. Runs in Ultra maxed out on 24" screen 1080p with my hardware.
Hi

If that is the case, looks like only one card was working when hooked up to the HDTV or may be 24Hz bug over HDMI [set the HDTV Scale to 16:9]

If launched through Origin try; alt enter twice [have this with crysis 3 v-sync and crossfirex do not work untill doing this on my rig]

run GPU-Z in background, select second HD 7950 check that

AC3 and all other HDMI audio pass-thru has zero impact on the video. Once again I'm going to call shenanigans.
Ok, sure I'll bite. So what "shenanigans" are you referring to?
Edit: ok, you thought I meant AC3 audio, not AC3 as in Assassins Creed 3 which is what I meant.

Launched AC3 through the default Uplay, not Origin.

Cards are indeed set to Crossfire.
Not a 24Hz bug.

I'm going to try a few things.
1) update CCC
2) update Steam and try other games, like Skyrim

Why are you on Cat12.11? Should you not be using Cat13.2 Beta drivers in the first place?

My second 6870 did that a couple times lately. Completely shut your computer off for a moment, restarting didn't work when this happened to me.
